Fig 3. The velocity results of the CFD computations in a plane through the center of phantom 1 and its two reconstructions.

In all models a jet forms at the neck of the stenosis and directly distal of the stenosis a recirculation zone is observed. A: Results in the phantom model. B: Reconstruction based on the segmentations from reader 1. C: Reconstruction based on the segmentations from reader 2. D: General streamlines observed in the computations.
